Honestly the way the game looks its going to be amazing, but there is still one thing they can fuck up on, Difficulty. Atleast for me that would totally remove all the immersion. Having to do preparations for quests, play carefully and observe would be really nice. Not just a difficulty option that usually makes thing simply unfair.
Monster hunter'ish for those who played that game, god thats a great game. That forced you to individually prepare for every hunt.
